Two-time wire-drawing device

Abstract

The invention discloses a two-time wire-drawing device. The device comprises a first wire drawing mechanism and a second wire drawing mechanism which are arranged in parallel, and a roller which is driven by a motor, wherein a first wire drawing mold is arranged on the first wire drawing mechanism; a second wire drawing mold is arranged on the second wire drawing mechanism; a vertical supporting board is arranged in front of the first wire drawing mechanism and the second wire drawing mechanism; a pretreatment mechanism of a reinforcing bar surface layer, which consists of a roller system and a guiding ring, is arranged on one side of the vertical supporting board, and a reversing wheel used for guiding a reinforcing bar is arranged on the other side of the vertical supporting board; a first coiling part and a second coiling part for coiling the reinforcing bar are arranged on the roller; the diameter of the first coiling part is smaller than that of the second coiling part. According to the device disclosed by the invention, after the reinforcing bar delivered by the roller system passes through the first wire drawing mold of the first wire drawing mechanism, the reinforcing bar bypasses the first coiling part and is reversed for two times by the reversing wheel for entering the second wire drawing mold of the second wire drawing mechanism for performing wire drawing and diameter reduction; the reinforcing bar is coiled on the second coiling part on the roller, so that the two-time wire drawing of the reinforcing bar is realized.

Description

technical field [0001] The invention relates to the field of steel bar processing, in particular to a double wire drawing device for steel bars. Background technique [0002] When using steel bars, due to different use environments and purposes, there are often different requirements for the diameter of steel bars, and if users purchase steel bars that meet the requirements according to these requirements, it will often cause a lot of waste. Wire drawing, so that it can be processed by a wire drawing machine to reduce the diameter to meet the required diameter requirements. However, in some cases, the diameter reduction of the steel bar is relatively large. If the wire is drawn once, the power consumption is relatively large, and the steel bar itself The physical properties, especially the strength, are greatly affected, which is not conducive to construction safety. Therefore, it is necessary to double-draw the steel bar to gradually reduce the diameter of the steel bar to ...

[0002] When using steel bars, due to different use environments and purposes, there are often different requirements for the diameter of steel bars, and if users purchase steel bars that meet the requirements according to these requirements, it will often cause a lot of waste. Wire drawing, so that it can be processed by a wire drawing machine to reduce the diameter to meet the required diameter requirements. However, in some cases, the diameter reduction of the steel bar is relatively large. If the wire is drawn once, the power consumption is relatively large, and the steel bar itself The physical properties, especially the strength, are greatly affected, which is not conducive to construction safety. Therefore, it is necessary to double-draw the steel bar to gradually reduce the diameter of the steel bar to ensure that it has good strength.
